- Abstract:
- Through satellite shot,ground survey and geologic exploration,we had a new understanding of the activity and slip rate on Southern margin fault of Chaiwopu basin since Late Pleistocene.It was suggested that this active fault once had strong activities since Late Pleistocene.Latest activity of the fault has leaped sand gravel stratum during Holocene at I river terrace with vertical displacement of 20～40 cm and colluvial wedge of 50cm,and has also leaped fine gravel landform with horizontal bedding during Late Pleistocene at II river terrace with vertical displacement of more than 9m,horizontal shortening displacement of more than 50m,vertical activity rate of 0.09mm/a since Late Pleistocene and horizontal shortening rate of 0.5mm/a.In addition,the activity of Banfanggou fault,which is the branch of the Southern margin fault of Chaiwopu basin,latest proof of leaping gravel landform at I river terrace.
